Rocaris 5 Pack Step Drill Bit & Countersink Set – Titanium Coated, 50 Sizes

All-in-one metal drilling kit you can trust

Rocaris delivers a compact, high value drilling kit designed for metal projects and DIY work. This set combines five step drill bits with five countersink bits, all enhanced with a titanium coating for durability. An ergonomic aluminum case keeps each piece organized and ready for your next project.

Versatile sizing in a single kit

Get dozens of hole sizes without juggling multiple bits. The stepped geometry compresses 50 traditional sizes into five bits, paired with countersinks for clean screw seating. The included sizes cover common metal work ranges, making file drops and on-site adjustments faster and more predictable. A center punch helps you start holes accurately before drilling.

• Replaces 50 sizes with 5 step bits plus 5 countersinks
• Titanium coating reduces friction for cooler, longer cutting life
• 118 degree split tip and double groove design for self centering and chip clearance
• Aluminum storage case protects bits and simplifies transport
• Center punch is included to mark starting points with precision

Performance you can feel in everyday use

Crafted for aluminum and soft metals, these bits maintain sharpness under heat and resist corrosion. The titanium coating works with the steel core to minimize wear, while the self centering tip helps prevent wandering in material with light drafting and steady pressure. Chip flow stays clear, helping you maintain a smooth cutting cadence.

• Best suited for aluminum, plastics, and thin soft metals
• Use with a drill press or bench drill for thicker metals to optimize results
• Keep speeds appropriate and apply steady, light pressure for cleaner cuts
• Not recommended for thick wood or very hard metals

What you get and how to use it

Pack includes five stepped drill bits in matched sizes, five countersinks in corresponding diameters, a center punch, and a durable aluminum case for reliable storage. This setup supports a range of DIY projects, from hobby builds to small workshop tasks, offering a consistent approach to hole prep and finishing.

Tip for best results: mark the workpiece with the center punch, start with a pilot mark, and select the step size that aligns with your target hole diameter. For thicker metal, rely on a drill press to ensure stability and accuracy.
